Summary
Children’s Health in London and Luton (CHILL) is an NIHR-funded cohort study evaluating the impact of London’s Ultra Low Emission Zone (ULEZ) on children’s respiratory health.
Our study builds on CHILL by collecting physical activity (by accelerometer) and travel patterns (by GPs) in the 3,300 children taking part. We test the hypothesis that a city-wide environmental intervention improving air quality and reducing traffic flows will improve children’s physical activity and reduce rates of obesity.
